XD they'll ignore it after a while. I never let it cover my tank surface entirely. But if they do, the betta will just push through and breathe from the surface anyway, I've seen them do this. if it grows well, you'll be throwing them out by the handful :) and best of all, you'll see no more ammonia XD Ur throwing ammonia away by the handful! woot!

Edit: my terrinle typos
edit:2 ^ see!

Wait you can throw ammonia away in a bowl my Carter used to live in it is 1 gallon he lives in a 10 gallon but the surface was covered in duckweed and crystalwort. The water was green there was a 15 watt light bulb above it and a plastic bad below the light to keep the Betta in there and Humidity.

You just keep scooping it up and throwing it away to keep it contained, if you don't want total cover just throw away what you don't want, it will keep multiplying like crazy, so just throw it away again and again

What I'm going to do is place a straw from work across the top so its got its half to grow.

My local pet store just gave it away they have a tank full of plants and that is growing at the top.
They gave me some and what I don't have in my tank is outside in the sun. Does it need to be in a heated tank.
